Post script and Non Post Script Printers

[alwaysanewbie]

I am working on a Printing related project and I dont have much
knowledge about printers.

Can someone send me links/info on the basic difference between
Postscript and Non Postscript printers?

I am interested in learning what their drivers write to the PRN files
and if they do write any Printer/machine/date and time specific
metadata.

Any information will be of great help.

Thank you very much.

This is a wide-open question.

Postscript drivers will write Postscript code to the PRN file or
device. A PCL driver will write PCL. Other drivers write whatever
sort of data/information is required for that particular printer.

I'm not familiar with PCL or other Page Description Languages, so I
won't try to discuss them further. I have a small understanding of the
Postscript language. It is a programming language (with loops,
variables, execution control statements, etc.). It also has some
built-in operators that work well for making marks on a page. Of
course, this is by design, and is a reason that Postscript is commonly
used as a printer language. A Postscript image can be device
independent, and thus can be printed on a variety of printers without
changing the program.
When printing to a Postscript printer, an acutal program is sent to
the printer. This program is executed, and the result is (usually)
that marks are made on a page and the page is printed.
If you want to learn more about the postscript language, look at
Adobe's site (www.adobe.com), look at comp.lang.postscript, or (if
you're feeling bold), get a copy of ghostscript for your computer, and
fiddle with it. It will run on most modern computers, and will let you
experience Postscript firsthand.

You may consider HP 2500 and 2550. Meanwhile, Konica Minolta 2300 an
2350 are also. My work is photo paper for photography printed b
entry-level color laser printer. Post Script or PCL6 printin
language is important to photographic printing to enhance gray leve
and sharpness of printing quality. If you want testing image, I ca

You have a lot of learning ahead. There are many books which describe
Postscript.

Can someone send me links/info on the basic difference between
Postscript and Non Postscript printers?

A Postscript printer has a unit which converts Postscript language into the
local printer language. Non Postscript printers expect files in their
native language.

I am interested in learning what their drivers write to the PRN files
and if they do write any Printer/machine/date and time specific
metadata.

Postscript files are simply text files with Postscript commands imbedded in
the lines. All Postscript files begin with "%!" and end with "!%". That is
the signal to the Postscript interpreter to intercept the rest of the file
for further processing.

Any information will be of great help.

Thank you very much.
